[Andrew Walker]

CVS commit by arwalker: 

Add the ability to interpret the x-axis values as various time formats, and display in another time format.

This is only a display of the concept at this point and the following issues need to be addressed:

* tick positioning
* permissible range of data
* reported position (for cursor and nearest data point)

In all of the above the algorithms use the raw data values, where they should be using/displaying the converted time values.

I will await comments before proceeding to fix this issues.
